TO ALL WHOM ll MAY CONCERN:

Be it known that I, PEAReE-K. Cenni., of Elkridgc Landing, inthe county ol Howard, and State of Maryland, have invented-certain new and useful Improvements in Water-Elevators for use in mines, lite.; andI do hereby declare that the following is a'full, clear, and exact description thereof, reference being had tothe accompanying drawings, making part ot' this` specification, and to the letters ofreferenee marked thereon, like letters indicating like parts wherever they occur. v

To enable others skilled in the art to construct and use my invention, I will proceed todescribe it.

My invention consists in arranging a series of bucketsin theform of an endless chain, and mounting them on a frame of novel construction, as hereinafter more fully described. v Figure 1 is a perspective view of my apparatus, as arranged for use in a mine or other` similar purpose. Figure 2 is n. front elevation, and I i Figure 3 is a side elevation of the same.

I construct a frame consisting of long timbers C, placed parallel, `and held by suitable cross-pieces. At right angles to these, on their inner sides, I attach a series of short pieces or cross-bars, a, projecting on each i side of the timbers C, as shown in figs. 1 and 3. To the upper ends of these pieces a, on their inner faces, `I f then bolt or otherwise secure long strips or timbers A, and corresponding with these, at the lower inner eudsot the cross-pieces a, I secure another set of strips or timbers B, as shown in the drawings, the timbers A and B,

when ythus arranged, constituting two railway tracks, one over the other, and parallel with each other. To the i side timbers C, at-both upper and lower ends, is secured a sprocket-wheel, D, one or both of which should `be `1 l mounted in adjustable bearings, for the purpose of tightening up the chai-n of buckets when required. I then construct a series of buckets, E, Yof the form represented in the drawings, and secure to each ci' them, outheirl under side, two rods o, which project at each side of the buckets, to for-m journals or axles, for the double purpose of uniting the buckets to each by metal links Zon each side, and also to form bearings for frictiomrollers n, which are provided with flanges like car-wheels, and are placed loosely on the journals` O ne of the rods or` journals o is attached at the lower end of the buckctslE, and the other is secured underneath'the centre of the bucket, as shown clearly in fig. 3. I then connect these buckets E by two metal links' Z, which are made ot",` g i proper length to reach from one to the other of the rods or axles o, and are'providcd with a hole at each-end,`of

around which a chain or cord, impasses, and by imparting motionA to the-wheel D, causes the chain of buckets to ascend on the rails A, and descend on theunderrails B. By this means, when the lower end of'the appa# ratus is immersed in thewater, the ascending hucketswill pass up full, and, as they pass over thempper Wheel D, will empty the water into a trough placcdto receiveit, as shown in iig.. 1, where the apparatus is represented in place in the shaft of a mine. By using the rails or track, and having the rollers n anged, there is ,less` friction and strain on the parts, and less power is required to operate it, and at` the sume time the linkse-nd 1 proper size to fit loosely on the journals. After slipping on the links ,onc ofthe ilanged rollers n is slipped "on to each end ofthe rod orjournals o, and the chain of buckets thus connected are hungin the frame in such a manner as to pass arouudthe sprocket-wheels D, at each end, and harethc rollers n. rest on the upper surface of the rails A and B, as shown in figs. 1 and 3. A pulley, t, is secured to the shaft of the upper wheel D,

rollers are kept from working oli' the journals while still being loose, so as to be readily removed whenever necessary for any purpose. In case very long series of buckets are required, it will be desirable to locate i severaliot" the wheels D at suitable distances along the frame,.and connect them on the outside of the frame by meansoi sprocket-wheelsand chains, or some similar means, inorder to relieve the links and journalsof the 'excessive strain and wear that would be otherwise thrown upon them.

It is obvious that the apparatus may be used also as adredge or excavator for clearing out channels, docks, Btc., where the material to be raised consists of mud, sand, or other soft substance. When used for such purposes it would be safer to secure the rollers to the journals inisueh a manner as to prevent the possibilityof their becoming detached. v

A simple form of consti-noting the journals -is to use a simple round rod, and pass it through lugs or cars lattached to the under side of the buckets, so that when worn, or it is desired for any purpose to separate` the chain of buckets, the rod can be withdrawn; or they may consist of short journals, bolted or otherwise secured os, s4? 2 to the buckets. Where the buckets are large, and the amount to be raised is large, it will be desirable to secure iron rails .to the timbers composing the tracks, as represented by e of fig, 2, for the rollers '/1y to run on, and

to loperate substantially as described.

thus prevent wear.

Having thus described my invention, what I claim is- A water-elevator, consisting Aof a series of buckets E, having journals attached as described, and connected by the detachable links Zwith the flanged rollers n applied to 'the journals,tl1c whole mounted in a suitable frame, having tracks and B for guiding and supporting the series of buckets, all constructed and arranged PE ARGE K.
